The Impact of COVID-19 Pandemics on the Development of Health Risk Communication: Challenges and Opportunities.

Starting from an analysis of communication in Italy during the COVID-19 emergency period (February-June 2020), this paper provides an overview of the main challenges and opportunities for communication during pandemics. The purpose of this study is to perform a literature review contributing to the identification of practical recommendations for the improvement of current risk communication strategies. Given the variety of the parties involved in communication and the peculiarity of the theme, an integrated analysis approach was adopted, based on the connections between institutional, scientific and mass communication. On one hand, the "emotional" character of Italian institutional communication aimed at promoting solidarity and unity among citizens. On the other hand, scientific communication played a key role both as a technical and scientific consultation for the policymaker, and as a guide for mass communication. Nevertheless, a lack of awareness emerged from the institutional and scientific side of the importance of an interface between science and effective, transparent policy. It thus becomes necessary to develop new and effective communication strategies aimed at facing uncertainties and the challenges of risk communication in epidemics and pandemics. Such strategies should consider interaction between public health, human and social sciences, political science, law, ethics, communication and media studies, as each of these areas may give an important contribution to the understanding of the context in which communication occurs.

Global Policy Responses to the COVID-19 Pandemic: Results of the ICOH Survey.

Background: On the basis of its role for the development of occupational health research, information, good practices, the International Commission on Occupational Health (ICOH) launched the present survey to collect information on public health and prevention policies put in place by the governments of the countries in the world to contain the pandemic. Methods: A cross-sectional study was conducted through an online questionnaire focused on COVID-19 data, public health policies, prevention measures, support measures for economy, work, and education, personal protective equipment, intensive care units, contact tracing, return to work, and the role of ICOH against COVID-19. The questionnaire was administered to 113 ICOH National Secretaries and senior OSH experts. Collected data refer to the period ranging from the beginning of the pandemic in each country to June 30, 2020. Results: A total of 73 questionnaires from 73 countries around the world were considered valid, with a 64.6% response rate. Most of the respondents (71.2%) reported that the state of emergency was declared in their country, and 86.1% reported lockdown measures. Most of the respondents (66.7%) affirmed that the use of face masks was compulsory in their country. As for containment measures, 97.2% indicated that mass gatherings (meetings) were limited. Regarding workplace closing, the most affected sector was entertainment (90.1%). Conclusion: The results of this survey are useful to gain a global view on COVID-19 policy responses at country level.

1-year radiological, functional and quality-of-life outcomes in patients with SARS-CoV-2 pneumonia - A prospective observational study.

All over the world, SARS-CoV-2 pneumonia is causing a significant short and medium-term morbidity and mortality, with reported persisting symptoms, radiological and lung alterations up to 6 months after symptoms onset. Nevertheless, the 1-year impact on affected patients is still poorly known. In this prospective observational study, 39 patients with SARS-CoV-2 pneumonia were recruited from a single COVID-19 hospital in Southern Switzerland. They underwent a 3-month and 1-year follow-ups. At 1 year, 38 patients underwent functional follow-up through lung function tests and six minutes walking test and submitted SF-12 and SGRQ questionnaires about health-related quality of life. At 1 year most of the patients showed a persistence of the radiological and functional abnormalities and a reduction of the health-related quality of life. Thirty patients (96.8%) still presented some residual abnormalities on CT scans (31 patients at 3 months), though with a general reduction of the lesional load in all lung lobes. Twenty patients (52.6%) had persisting lung function tests impairment, with an overall improvement of DLCO. As concerning the functional status, lowest SpO2 during 6MWT increased significantly. Finally, 19 patients (50%) reported a pathological St. George's Respiratory Questionnaire, and respectively 12 (31.6%) and 11 (28.9%) patients a pathological Short Form Survey-12 in physical and mental components. At 1-year follow-up SARS-CoV-2 pneumonia survivors still present a substantial impairment in radiological and functional findings and in health-related quality of life, despite showing a progressive recovery.

The future of scientific conferences in the era of the COVID-19 pandemic: Critical analysis and future perspectives.

The global spread of COVID-19 pandemic forced the scientific community to identify new ways of exchanging and transferring the scientific knowledge, also considering that the measures taken to combat the pandemic, such as travel restrictions, closed borders and gathering bans, led to cancellations of many conferences, meetings and workshops. The enhancement of the existing digital platforms and the development of new systems to share scientific knowledge has allowed the scientific community to "meet" again in new virtual environments (e.g., Zoom, Cisco WebEx, Live Stream, Demio, GoToWebinar Seminar, Google Hangouts, Skype, Microsoft Teams, etc.), providing an unprecedented opportunity to reform methods of organizing academic conferences in all disciplines.Starting from the review of the existing literature, this study aimed at investigating the impact of the spreading of virtual conferences on the field of research. The SWOT analysis was used to identify strengths and weaknesses of the scientific conferences organized in the new format, as well as opportunities and threats created by the socio-economic and political context in the era of the COVID-19 pandemic.

Impact of tiered restrictions on human activities and the epidemiology of the second wave of COVID-19 in Italy.

To counter the second COVID-19 wave in autumn 2020, the Italian government introduced a system of physical distancing measures organized in progressively restrictive tiers (coded as yellow, orange, and red) imposed on a regional basis according to real-time epidemiological risk assessments. We leverage the data from the Italian COVID-19 integrated surveillance system and publicly available mobility data to evaluate the impact of the three-tiered regional restriction system on human activities, SARS-CoV-2 transmissibility and hospitalization burden in Italy. The individuals' attendance to locations outside the residential settings was progressively reduced with tiers, but less than during the national lockdown against the first COVID-19 wave in the spring. The reproduction number R(t) decreased below the epidemic threshold in 85 out of 107 provinces after the introduction of the tier system, reaching average values of about 0.95-1.02 in the yellow tier, 0.80-0.93 in the orange tier and 0.74-0.83 in the red tier. We estimate that the reduced transmissibility resulted in averting about 36% of the hospitalizations between November 6 and November 25, 2020. These results are instrumental to inform public health efforts aimed at preventing future resurgence of cases.

Risk assessment at work and prevention strategies on COVID-19 in Italy.

The COVID-19 pandemic has spread worldwide, with considerable public health and socio-economic impacts that are seriously affecting health and safety of workers, as well as their employment stability. Italy was the first of many other western countries to implement extended containment measures. Health workers and others employed in essential sectors have continued their activity, reporting high infection rate with many fatalities. The epidemiological trend highlighted the importance of work as a substantial factor to consider both when implementing strategies aimed at containing the pandemic and shaping the lockdown mitigation strategy required for sustained economic recovery. To support the decision-making process, we have developed a strategy to predict the risk of infection by SARS-CoV-2 in the workplace based on the analysis of the working process and proximity between employees; risk of infection connected to the type of activity; involvement of third parties in the working processes and risk of social aggregation. We applied this approach to outline a risk index for each economic activity sector, with different levels of detail, also considering the impact on mobility of the working population. This method was implemented into the national epidemiological surveillance model in order to estimate the impact of re-activation of specific activities on the reproduction number. It has also been adopted by the national scientific committee set up by the Italian Government for action-oriented policy advice on the COVID-19 emergency in the post lockdown phase. This approach may play a key role for public health if associated with measures for risk mitigation in enterprises through strategies of business process re-engineering. Furthermore, it will make a contribution to reconsidering the organization of work, including also innovation and fostering the integration with the national occupational safety and health (OSH) system.
